    摘要:
    Acyclic 2:3,5:6- and 3:4,5:6-di-O-isopropylidene-D-glucoses have been converted by four reactions involving a Wittig chain homologation, a catalytic hydrogenation, an acid hydrolysis and an acetonation into 2,3-dideoxy-5:6,7:8-di-O-isopropylidene-D-gluco-octono-1,4-lactone which underwent a Wasserman reaction and then a hydrolysis to yield 3-deoxy-D-gluco-oct-2-ulosonic acid, isolated as its ammonium salt 2.

  • A synthesis of 2-deoxy-3-0-methyl-1,4-aldonolactones
    作者:F.J. Lopez Herrera、M.S. Pino Gonzalez

    日期:1986.1
    aldehyde sugars 1, (free or in lactol form), reacted with methyl hydrogen malonate to give α,β-unsaturated esters 2. In the case of lactols, the R group in 2 is not identical to the R in 1 (epimerisation occurs). Base-catalysed addition of methanol to the esters 2, afforded the epimeric ethers 3, acid hydrolisis of which yielded the 2-deoxy-3-0-methyl-1,4-aldonolactones 4. Degradation of the sugar chain
    到2-脱氧- 3-甲实用合成路线0 -甲基-1,4- aldonolactones得以实现。醛糖1的异亚丙基衍生物(游离或以乳糖醇的形式)与丙二酸氢甲酯反应生成α,β-不饱和酯2。在乳糖醇的情况下,2中的R基团与1中的R基团不相同(发生差向异构化)。将甲醇碱催化加成到酯2中,得到差向异构醚3,其酸水解产生2-脱氧-3- 0-甲基-1,4-醛内酯4。 C-3上的绝对配置。
  • A comparison of the Wittig and Knoevenagel–Doebner reactions for the chain extension of aldoses

    Reaction conditions are described for the chain extension of 2,3 : 5,6-di-O-isopropylidence-D-mannose (1) with a Wittig ylide (2) to give the acyclic manno-octenoate (3) or the C-glycofuranosides (4 and 5) and with the Knoevenagel–Doebner reaction to afford the isomeric gluco-octenoate (6); the isomerisation proved to occur in the latter reaction provides an explanation for an anomaly in the literature
